Here is a printable of a portrait of Henry II from the Google Art Project. It was done some time after his death so we can only guess that he looked liked this. He was a small man, but apparently quite strong.
This is the earliest known portrayal of the murder of Thomas Becket by four of Henry II's knights in Canterbury Cathedral, thought to have been done around 1200. It shows Becket praying at the altar of the Cathedral before he was killed.
